What's a good, actually reliable Android app for keeping track of the important comic books and their values? I need something that won't crash on me during my 12-hour shifts!

Okay, so I've been using Key Collector Comics for a while now, and honestly, it's a lifesaver. I'm too tired to learn complicated apps, but this one is a no-fuss approach to tracking key comic books. You know, the ones that are actually worth something! It's been really useful for me, especially when I'm trying to quickly check the value of something during a break at the clinic. It's got a surprisingly comprehensive database, and I can even make lists of comics I own or want to buy. The best part? It hasn't crashed once in the last six months. That's a win in my book, because I can't deal with unreliable apps when I'm already dealing with, well, everything else at the hospital. Honestly, it's just nice to have something that works when you need it.
